title: Ring opening of methylenecycloalkenes via the C-C bond cleavage.
abstract: 3-Methylenecycloalkene-1,1-dicarboxylates underwent facile ring opening via the cleavage of the unactivated C-C bond to yield aliphatic alkenes. The reaction (intramolecular deallylation) was catalyzed by "Ni-H" species generated in situ from a NiX2(phosphine) n/R3Al mixture and proceeded under ambient conditions. In addition, the skeletal rearrangement of a diene could be carried out by a one-pot cycloisomerization/deallylation sequence.
